Finally got this to work.. Although not sure if this is still related to
irq on driver issues on the network card..
But I was able to insert a PCI express network card and got this going ..
The issues still stays if I use both ports on the dual network card.. i.e
to make this work I had to configure one network on the motherboard and
the other on the pciexpress network card.. the server crashes if I use
both nics on the motherboard or the pciexpress network card..

Derrick

Does it hang immediatly after enabling the second nic, or some time later
? if you can enter ddb, does 'show events' report interrupts for this nic
?

It looks like an interrupt routing issue. I'm not an expert in this area;
a PR with the dmesg and ACPI infos would probably be the best way to get
this handled.
